Для получения потомства сформированы 4 группы родительских пар 1,5- и 2,5-летнего возраста. Потомство от пар «матки 1,5 лет × бараны 2,5 лет», «матки 2,5 лет × бараны 2,5 лет» преобладало по живой массе над аналогами «матки 1,5 лет × бараны 1,5 лет», «матки 2,5 лет × бараны 1,5 лет» на 8,23; 3,23% и 6,29; 1,38% (р ≥ 0,99). Молодняк от пар «матки 2,5 лет × бараны 1,5 лет» превосходил животных от сочетаний «матки 1,5 лет × бараны 1,5 лет», «матки 2,5 лет × бараны 1,5 лет», «матки 2,5 лет × бараны 2,5 лет» на 5,26% (р ≥ 0,95), 3,77%, 2,08% (р ≥ 0,95), 4,04% (р ≥ 0,95), 2,39% и 2,8%. У молодняка от пар «матки 2,5 лет × бараны 1,5 лет» был выше выход шерсти, чем от пар «матки 1,5 лет × бараны 1,5 лет», «матки 1,5 лет × бараны 2,5 лет», «матки 2,5 лет × бараны 2,5 лет», на 0,1%, 0,8% и 1,2% (р ≤ 0,95). В Поволжье для продуктивного использования овец ставропольской породы целесообразно сочетание родительских пар «матки 1,5 лет × бараны 2,5 лет» и матки «2,5 лет × бараны 2,5 лет».</p></abstract><trans-abstract xml:lang="en"><p>The productivity of the progeny of Stavropol sheep from parental pairs of different ages was studied. To obtain offspring, 4 groups of parent pairs of 1.5- and 2.5-year-olds were formed. Offspring from pairs of “1.5-year-old uterus × 2.5-year-old sheep”, “2.5-yearold uterus × 2.5-year-old sheep” prevailed in live weight over analogues of “1.5-year-old uterus × 1.5-year-old sheep”, “2.5-year-old uterus × 1.5-year-old sheep” by 8.23; 3.23% and 6.29; 1.38% (p ≥ 0.99). Young animals from pairs of “2.5-year-old uterus × 1.5-yearold sheep” outperformed animals from combinations of “1.5-year-old uterus × 1.5-yearold sheep”, “2.5-year-old uterus × 1.5-year-old sheep”, “2.5-year-old uterus × 2.5-yearold sheep” by 5.26% (p ≥ 0,95), 3,77%, 2,08% (p ≥ 0.95), 4.04% (p ≥ 0.95), 2.39% and 2.8%. Young animals from pairs of “2.5-year-old uterus × 1.5-year-old sheep” had a higher wool yield than from pairs of “1.5-year-old uterus × 1.5-year-old sheep”, “1.5-year-old uterus × 2.5-year-old sheep”, “2.5-year-old uterus × 2.5-year-old sheep”, by 0.1%, 0.8% and 1.2% (p &lt; 0.95). In the Volga region, for the productive use of Stavropol sheep, it is advisable to combine parental pairs of “1.5-year-old uterus × 2.5-year-old sheep” and “2.5-year-old uterus × 2.5-year-old sheep”.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>овца</kwd><kwd>порода</kwd><kwd>спаривание</kwd><kwd>продуктивность</kwd><kwd>живая масса</kwd><kwd>настриг шерсти</kwd><kwd>возраст</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sheep</kwd><kwd>breed</kwd><kwd>pairinq</kwd><kwd>productivity</kwd><kwd>live weiqht</kwd><kwd>shearing of wool</kwd><kwd>age</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Трухачев В.И., Мороз В.А., Селионова М.И.
